有机氯农药的测定方法有气相色谱法、薄层层析法等。气相色谱法具有分离能力强、快速、灵敏度高的优点,但受设备条件的限制不易普及。薄层层析法则具有设备简单、分离能力强、易于推广等优点,目前已广泛的应用于农药残留的检验。但由于此法技术操作要求严,条件不易控制,难于标准化,造成结果不稳定,定量困难。为此,我们对薄层层析法进 Determination of organochlorine pesticides gas chromatography, thin-layer chromatography and so on. Gas chromatography has the advantages of strong separation, fast, high sensitivity, but not easy to popularize by the equipment conditions. Thin-layer chromatography has the advantages of simple equipment, strong separation ability, easy to popularize and so on. It has been widely used in pesticide residue inspection. However, due to the strict technical operation of this method, the conditions are not easy to control and difficult to standardize, resulting in unstable results and quantitative difficulties. To this end, we advanced the TLC method
